Set in the year 1861, Matt Colter, a mountain man is traveling across the great divide with his young Native bride, Little Doe.

They cross paths with a Paiute party, a beautiful young woman Wannetta watches the mountain man and his pretty Native bride.

Little Doe finds bone remains and later tells Matt that the shelter they rebuilt, the cabin, that unbeknownst to them, is on sacred Paiute burial ground.

Matt leaves with his newborn baby and meets up with a lone mountain man who tells him he needs to feed the child.

The Paiute war party later places a signal for Wannetta to kill the mountain man's horse so they will be forced to travel on foot.

Determined to find his son, Colter seeks the help of his friend, mountain man Lum Witcher.
